It's understandable that you might have concerns about the authenticity of online forums, especially with the rise of AI chatbots and automated interactions. While I can't provide specific numbers, I can offer some insights to consider when approaching these questions.

1. Diverse Community: Many online forums consist of a diverse community of individuals who share their opinions, thoughts, and experiences. While there might be AI chatbots present, the majority of users are likely real people with genuine perspectives.

2. Moderation and Rules: Reputable forums usually have moderation systems in place to ensure that discussions remain meaningful and respectful. This helps filter out any automated or irrelevant content.

3. Engagement and Conversation: Authentic forums thrive on meaningful interactions and discussions. Genuine users seek engagement and thoughtful responses, so you're likely to find real people who are interested in exchanging ideas.

4. Varied Responses: When you post opinions, thoughts, and articles, you're likely to receive a range of responses that reflect the diversity of human perspectives. This variety can be a sign that you're interacting with real individuals.

5. User Profiles and Histories: Many forums allow users to create profiles, share personal information, and showcase their history of interactions. This can help you identify genuine users over automated entities.

6. Specific Expertise: In some forums, users might have specific expertise or experiences that contribute to valuable discussions. This expertise can be an indicator of real human participation.

7. Community Building: Online forums provide spaces for people to connect, share knowledge, and build relationships. This aspect of community building often leads to genuine interactions.

Ultimately, the decision to participate in online forums depends on your comfort level and goals. If you're concerned about the authenticity of interactions, you can focus on engaging with users who provide thoughtful responses, display genuine interest, and contribute meaningfully to the discussions. Remember that while AI chatbots are becoming more prevalent, they are still not the majority of participants on most reputable forums.
